Abstract: An improved heat treatment fixture is disclosed formed in a tubular frame network structure composed of mating plural cylindrical tubings segments and cast couplings which are interconnected by pins to permit moderate movement within the frame network structure during the heat treatment process, and thereby. relieve thermal stresses developed within a fixture. The tubing frame network structure renders the fixture lightweight and is adapted to permit multiple fixtures to be rapidly linked together in an end to end orientation to vary the size and capacity of the fixture. The fixture is further constructed to allow rapid repair by the end user to prolong the useful life of the fixture and includes a part tray which is replaceable directly within the field.

Abstract: A chemical heat pump system is disclosed for use in heating and cooling structures such as residences or commercial buildings. The system is particularly adapted to utilizing solar energy, but also increases the efficiency of other forms of thermal energy when solar energy is not available. When solar energy is not available for relatively short periods of time, the heat storage capacity of the chemical heat pump is utilized to heat the structure, as during nighttime hours. The design also permits home heating from solar energy when the sun is shining. The entire system may be conveniently rooftop located. In order to faciliate installation on existing structures, the absorber and vaporizer portions of the system may each be designed as flat, thin wall, thin pan vessels which materially increase the surface area available for heat transfer.

Abstract: A method and apparatus for conducting an immunoassay. The apparatus features a cylindrical tube having one open end into which a plunger filter assembly is slidably fitted. The filter assembly is composed of a plunger filter cylinder open at both ends, a seal fixed to the proximal end of the plunger filter cylinder and a dome-shaped filter inside of and closing the proximal end of the plunger filter cylinder, and beads sensitized with an immunologically reactive material, such as an antibody.

Abstract: An improved hydraulic mining tool apparatus for the recovery of minerals from subterranean formations is disclosed wherein the drill string, which extends from ground surface into the mineral deposit, is adapted to be maintained stationary during the mining operation while the mining tool, mounted to the lower end of the drill string, is adapted to rotate within the mineral formation. By maintaining the drill string stationary within the formation, frictional drag forces and tortional forces exerted on the apparatus are minimized thereby substantially reducing the input power requirements and reducing the possibility of a twist-off of the mining tool within the formation.

Abstract: A pedestal for CRT's, video screens, projection consoles, disk drives, and other consoles which have a face or screen permitting limited pivotal and limited forward and back tilt movement, wherein movement is permitted against constant frictional forces sufficient to hold the console in any desired position by means of a hollow partially spherical journal, and bearings in resilient compression against the convex and concave surfaces of the journal.

Abstract: An improved drill section and method of hydraulically mining mineral deposits which includes plural flow conduits extending through the drill section, having complimentary shaped tapered thread sections at opposite ends thereof, is disclosed. The tapered thread sections distribute and accommodate high tortional forces and ensure registered alignment of the flow conduits. Seals are provided at the interface between the multiple drill sections which simultaneously seal each of the flow conduits positioned within the interior of the drill sections. The outer casing of the drill section permits the introduction of high pressure fluid and includes a plurality of pressure-responsive plugs adapted to rupture at a predetermined pressure value thereby releasing fluid to lubricate the drill string and reduce the torque encountered during the mining operation.

Abstract: An anchoring mechanism for preventing the counter-rotation of a motor driven wrench in reaction to the torque produced by the turning of a tool member therein has a multiplicity of members tandemly hinged together, one end member having elements for attaching to a motor driven wrench and the other end member having elements for securing to a fixed reference base whereby the motor driven wrench is prevented from rotating in reaction to the turning of a tool member therein.

Abstract: An improved fruit drying system particularly suited for large scale commercial drying application is disclosed, comprising a plurality of substantially rigid transparent hoods, each sized to be positioned over the fruit to be dried to increase the drying effect of solar radiation and including vent means for providing convectional air flow across the fruit during the drying process. The hoods are adapted to be arranged in a side by side orientation directly within the growing field and be rapidly interlocked to one another whereby a composite hood assembly is yielded. The hood assembly forms an effective shroud over the fruit which prevents exposure of the fruit to moisture and/or animal predators during the drying process.

Abstract: An improved apparatus and method for hydraulically mining unconsolidated subterranean mineral formations is disclosed wherein the hydraulic mining tool and surface drilling equipment is supported upon elongate structural beams releasably affixed at opposite ends to laterally spaced concrete foundations positioned upon the drilling site. The structural beams prevent the mining tool from canting or subsiding during the hydraulic mining process and may be reused for consecutive mining operations at differing locations upon the drilling site. An improved mining tool configuration is additionally disclosed which is specifically adapted to agitate and maintain the mined minerals in suspension within the mining slurry and further direct the slurry toward the mining tool for subsequent transport to ground surface.

Abstract: Process and apparatus for recovering volatile distillates from coal, and other solid carbonaceous fuel sources, by heating the top surface of a bilayer of coal formed of an upper layer of recycled coal and a lower layer of green coal, maintaining the lower level of green coal at a temperature cool enough to condense constituents distilled from the upper layer of recycle coal, and recycling the once passed green coal as recycle coal is disclosed.

Abstract: A Colles fracture fixature device comprised of a pair of curved, slotted frame members for received fixation pin holders having a pin bushing rotatably received in the bore of the fork arms of a clevis.

Abstract: Collagen affinity matrices are prepared, useful for separating collagenous substances from other high molecular weight proteinaceous substances. Fibronectin is fragmentated chemically or by enzymatic digestion, etc. Fragments of fibronectin, which retain the collagen-binding site but are severed from other binding sites of intact fibronectin, are selected and coupled to solid support material.

Abstract: Immunosuppressive agents which are conjugates of an antigen linked to a D glutamic acid:D-lysine copolymer are disclosed. Also disclosed are methods of preparing the conjugates and therapeutic methods for inducing immunological tolerance to antigens.
